"Our 2013 results show the early success of our strategies to drive accelerated customer growth. We now deliver a competitive, highly valuable suite of products and services to our customers, and we are beginning to execute at a high level, evidenced by improving trends through the year," said Tom Rutledge, President and CEO of Charter Communications. "We will continue that momentum in 2014, and plan to complete our all-digital initiative this year, allowing us to deliver a superior set of services across the vast majority of our footprint. Combined with improved service capabilities and higher customer satisfaction, these strategies are expected to result in greater market share and improving cash flow per home passed, as we position Charter for long-term growth and value creation."

On July 1, Charter completed its acquisition of Cablevision's Bresnan Broadband Holdings, LLC and its subsidiaries (collectively, "Bresnan"). As a result of the acquisition, Charter added cable operating systems in Montana, Wyoming, Colorado and Utah that pass approximately 670,000 homes and serve approximately 375,000 residential and business customers. All customer data referred to herein, are pro forma for the Bresnan transaction, as if it had occurred on January 1, 2012.

During the fourth quarter of 2013, Charter saw year-over-year and sequential improvement in customer relationship and PSU growth. Residential customer relationships grew by 63,000, up from 24,000 in the fourth quarter of 2012. Commercial customer relationships grew by 16,000 in the fourth quarter of 2013, compared to a gain of 4,000 in the prior-year period. Residential PSUs increased by 147,000 versus 57,000 in the year-ago quarter, while commercial PSUs increased 18,000 during the fourth quarter versus a gain of 12,000 in the year-ago quarter.

For the full year 2013, Charter added 172,000 residential customers compared to growth of 120,000 residential customers in 2012. In 2013, Charter also saw net additions improvement across every residential PSU category compared to the prior year, adding 415,000 residential PSUs, versus a gain of 296,000 in 2012, for a year-over-year improvement of 40.2%.

At the end of 2013, Charter had completed approximately 15% of its all-digital initiative, with customers in these markets generally having access to over 170 HD channels. All-digital allows Charter to offer more advanced products and services, and provides residential customers with two-way digital set-tops, which offer higher picture quality, an interactive programming guide and video on demand on all TV outlets in the home. Charter expects to complete its all-digital roll out across its footprint by year end 2014, at which time nearly all of Charter's residential customers will have access to Charter Spectrum, an industry-leading suite of video, data, and voice services that will include over 200 HD channels, in addition to minimum offered Internet speeds of 60 Mbps, and a fully featured voice service at a highly competitive price.

Residential video customers declined by 2,000 in the fourth quarter of 2013, versus a loss of 36,000 in the year-ago period. The year-over-year improvement in video net adds was driven by a more competitive video product, including more HD channels, attractive packaging of advanced services, including Charter's new TV app, our transition to new selling methods, and improved service quality.

Charter added 93,000 residential Internet customers in the fourth quarter of 2013, compared to 59,000 a year ago. The Company continues to see strong demand for its Internet service as consumers value the speed and reliability of Charter's Internet offering. As of December 31, 2013, approximately 75% of Charter's residential Internet customers subscribed to tiers that provided speeds of 30 Mbps or more.

During the fourth quarter, the Company added 56,000 residential voice customers, versus a gain of 34,000 during the fourth quarter of 2012. For the full year 2013, Charter added 200,000 voice customers versus 134,000 in 2012, an improvement of 49.3%.

Fourth quarter residential revenue per customer relationship totaled $107.97, and grew by 2.1% on a pro forma basis, from $105.76 in the fourth quarter of 2012, driven by rate adjustments, higher product sell-in and promotional rate step-ups, partially offset by the migration of legacy customers to Charter's new pricing and packaging and continued single play Internet sell-in.

COSTS AND EXPENSES:

Total operating costs and expenses (excluding depreciation and amortization)

Internet revenues grew 15.0% on a pro forma basis compared to the year-ago quarter to $590 million, driven by an increase of 324,000 Internet customers during the last year and by price adjustments. On an actual basis, Internet revenues grew 22.4% year-over-year.

Voice revenues totaled $154 million, down 22.6% on a pro forma basis versus the fourth quarter of 2012, due to value-based pricing and revenue allocation from higher bundling, partially offset by the addition of 200,000 voice customers in the last twelve months. Voice revenues declined 17.2% year-over-year, on an actual basis.

Commercial revenues rose to $228 million, an increase of 19.4% on a pro forma basis over the prior-year period, and was driven by higher sales to small and medium businesses and to carrier customers. On an actual basis, commercial revenues grew 28.8% year-over-year.

Fourth quarter advertising sales revenues of $83 million declined 17.8% on a pro forma basis compared to the year-ago quarter, driven by a decline in political advertising revenue, which saw strength in the fourth quarter of 2012, given local and national elections. Advertising sales declined 13.5% year-over-year, on an actual basis.

Operating Costs and Expenses

Fourth quarter total operating costs and expenses increased 6.5% on a pro forma basis compared to the year-ago period, reflecting increases in programming costs, marketing expenses, and other expenses.

Fourth quarter programming expense increased by $38 million on a pro forma basis, or 7.3%, as compared to the fourth quarter of 2012, reflecting contractual programming increases and higher expanded basic package penetration. Marketing costs increased by $21 million on a pro forma basis, or 19.8% as compared to the fourth quarter of 2012, reflecting increased sales activity and sales channel development. Other expenses grew by $28 million on a pro forma basis, or 15.4%, as compared to the fourth quarter of 2012, reflecting higher labor costs to support commercial revenue growth and higher collection costs. On an actual basis, total operating costs and expenses grew by 13.9% year-over-year.

Adjusted EBITDA

Fourth quarter Adjusted EBITDA of $764 million grew by 2.6% year-over-year on a pro forma basis, reflecting pro forma revenue growth and operating costs and expenses growth of 5.0% and 6.5%, respectively. On an actual basis, Adjusted EBITDA grew by 9.5% compared to the year-ago quarter, primarily driven by the acquisition of Bresnan. Adjusted EBITDA margin declined to 35.6% versus the prior year period on both a pro forma and actual basis, given higher programming and growth-related expenses and lower high margin political advertising.

Net Income

Net income totaled $39 million in the fourth quarter of 2013, compared to a net loss of $73 million on a pro forma basis and $40 million on an actual basis in the year-ago period. Net income increased year-over-year on a pro forma basis primarily due to higher income from operations and a $4 million tax benefit in the fourth quarter of 2013 versus a $75 millionpro forma tax expense in the fourth quarter of 2012. The tax benefit was primarily related to a partnership restructuring in the fourth quarter of 2013, as well as refinancing transactions completed in 2013. Basic net income per common share was $0.38 in the fourth quarter of 2013 compared to net loss per common share of $0.73 on a pro forma basis, and $0.41 on an actual basis during the same period last year. The increase was primarily the result of the factors described above.

Capital Expenditures

Property, plant and equipment expenditures were $566 million in the fourth quarter of 2013, compared to $469 million on a pro forma basis and $449 million on an actual basis, during the fourth quarter of 2012. The increase was primarily driven by higher spending on customer premise equipment to support customer growth and Charter's all-digital initiative, and higher spending on scalable infrastructure and support capital.

Cash Flow

During the fourth quarter of 2013, net cash flows from operating activities totaled $595 million, compared to $485 million in the fourth quarter of 2012. The increase in net cash flows from operating activities was primarily related to an increase in Adjusted EBITDA and the timing of cash interest payments.

Free cash flow for the fourth quarter of 2013 was $84 million, compared to $33 million during the same period last year. The increase was primarily due to higher cash flow from operating activities versus the prior-year period, partially offset by higher capital expenditures.

Revenue

For the year ended December 31, 2013, pro forma revenues rose to $8.4 billion, 5.0% higher on a pro forma basis than in 2012, driven by continued growth in Internet, video and commercial revenues. On an actual basis, full year 2013 revenues rose 8.7% year-over-year.

Operating Costs and Expenses

Pro forma operating costs and expenses totaled $5.5 billion in 2013, an increase of 6.2% on a pro forma basis compared to the year-ago period, reflecting increases in programming costs, costs to service customers, marketing expenses, and other expenses. On an actual basis, total operating costs and expenses grew by 10.1% year-over-year.

Adjusted EBITDA

Pro forma Adjusted EBITDA was $2.9 billion for the year ended December 31, 2013, an increase of 2.9% compared to 2012, on a pro forma basis. On an actual basis, Adjusted EBITDA grew by 6.1% compared to the year-ago period, driven by higher organic revenue growth and the acquisition of Bresnan. Charter's Adjusted EBITDA margin declined year-over-year, on both a pro forma and actual basis, to 35.0%.

Net Loss

For the year ended December 31, 2013, pro forma net loss was $194 million, compared to $392 million on a pro forma basis, in 2012. Net loss decreased year-over-year primarily due to lower income tax expense, lower interest expense, and higher income from operations. The lower tax expense in 2013 was primarily related to a $4 million tax benefit in the fourth quarter related to a partnership restructuring, as well as refinancing transactions completed in 2013. On a pro forma basis, net loss per common share was $1.90 for the year ended December 31, 2013, compared to $3.93 on a pro forma basis in 2012. The decrease was the result of the factors described above, in addition to a 2.3% increase in weighted average shares outstanding in the last twelve months, driven primarily by the exercise of 4.5 million warrants in 2013.

On an actual basis, net loss for the year ended December 31, 2013, totaled $169 million, compared to $304 million in 2012. On an actual basis, net loss per common share was $1.65 for the year ended December 31, 2013, compared to $3.05, on an actual basis in 2012.

Capital Expenditures

On an actual basis, capital expenditures for the year ended December 31, 2013, totaled $1.8 billion, consistent with Charter's previously stated estimate, and compared to $1.7 billion in 2012. The year-over-year increase related to higher residential and commercial customer growth, as well as higher set-top box placement in existing homes, and expenditures for back-office support and for real estate related to our organizational realignment, and the acquisition of Bresnan.

Pro forma property, plant and equipment expenditures for the full year 2013, totaled $1.9 billion, compared to $1.8 billion in 2012.

In 2014, capital expenditures are expected to be approximately $2.2 billion, driven by Charter's all-digital transition including the deployment of additional set-top boxes in new and existing customer homes, growth in Charter's commercial business, and further spend related to efforts to insource service operations as well as product development. The actual amount of our capital expenditures will depend on a number of factors including the growth rates of both our residential and commercial businesses, and the pace at which we progress to all-digital transmission, which we anticipate will comprise approximately $400 million of 2014 capital expenditures.

Cash Flow

In 2013, net cash flows from operating activities totaled $2.2 billion compared to $1.9 billion in 2012. The increase in net cash flows from operating activities was primarily related to an increase in Adjusted EBITDA and the timing of cash interest payments.

Free cash flow for the year ended December 31, 2013 was $409 million, compared to $144 million during the same period last year. The increase was primarily due to higher cash flow from operating activities versus the prior-year, partially offset by higher capital expenditures.

Liquidity

Total principal amount of debt was approximately $14.2 billion as of December 31, 2013. At the end of the quarter, Charter held $21 million of cash and cash equivalents, and its credit facilities provided approximately $1.1 billion of additional liquidity.

Use of Non-GAAP Financial Metrics

The Company uses certain measures that are not defined by Generally Accepted Accounting Principles ("GAAP") to evaluate various aspects of its business. Adjusted EBITDA and free cash flow are non-GAAP financial measures and should be considered in addition to, not as a substitute for, net income (loss) or cash flows from operating activities reported in accordance with GAAP. These terms, as defined by Charter, may not be comparable to similarly titled measures used by other companies. Adjusted EBITDA is reconciled to net income (loss) and free cash flow is reconciled to net cash flows from operating activities in the addendum of this news release.

Adjusted EBITDA is defined as net income (loss) plus net interest expense, income taxes, depreciation and amortization, stock compensation expense, (gain) loss on extinguishment of debt, (gain) loss on derivative instruments, net and other operating expenses, such as special charges and (gain) loss on sale or retirement of assets. As such, it eliminates the significant non-cash depreciation and amortization expense that results from the capital-intensive nature of the Company's businesses as well as other non-cash or special items, and is unaffected by the Company's capital structure or investment activities. However, this measure is limited in that it does not reflect the periodic costs of certain capitalized tangible and intangible assets used in generating revenues and the cash cost of financing. These costs are evaluated through other financial measures.

Free cash flow is defined as net cash flows from operating activities, less purchases of property, plant and equipment and changes in accrued expenses related to capital expenditures.

Management and the Company's board of directors use adjusted EBITDA and free cash flow to assess Charter's performance and its ability to service its debt, fund operations and make additional investments with internally generated funds. In addition, adjusted EBITDA generally correlates to the leverage ratio calculation under the Company's credit facilities or outstanding notes to determine compliance with the covenants contained in the credit facilities and notes (all such documents have been previously filed with the United States Securities and Exchange Commission). For the purpose of calculating compliance with leverage covenants, we use adjusted EBITDA, as presented, excluding certain expenses paid by our operating subsidiaries to other Charter entities. Our debt covenants refer to these expenses as management fees which fees were in the amount of $54 million and $49 million for the three months ended December 31, 2013 and 2012, respectively, and $201 million and $191 million for the year ended December 31, 2013 and 2012, respectively.

In addition to the actual results for the three months and year ended December 31, 2013 and 2012, we have provided pro forma results in this release for the year ended December 31, 2013 and the three months and year ended December 31, 2012. We believe these pro forma results facilitate meaningful analysis of the results of operations. Pro forma results in this release reflect certain acquisitions of cable systems in 2013 as if they occurred as of January 1, 2012. Pro forma statements of operations for the year ended December 31, 2013 and the three months and year ended December 31, 2012 are provided in the addendum of this news release.

Pro forma operating statistics reflect certain acquisitions of cable systems in 2013 as if such transactions had occurred as of the last day of the respective period for all periods presented.

See footnotes to unaudited summary of operating statistics on page 6 of this addendum.

(a)

We calculate the aging of customer accounts based on the monthly billing cycle for each account. On that basis, at December 31, 2013, September 30, 2013 and December 31, 2012, customers include approximately 11,300, 9,700 and 18,400 customers, respectively, whose accounts were over 60 days past due in payment, approximately 800, 1,000 and 2,600 customers, respectively, whose accounts were over 90 days past due in payment and approximately 900, 900 and 1,700 customers, respectively, whose accounts were over 120 days past due in payment.

(b)

"Passings" represent our estimate of the number of units, such as single family homes, apartment and condominium units and commercial establishments passed by our cable distribution network in the areas where we offer the service indicated. These estimates are updated for all periods presented based upon the information available at that time.

(c)

"Penetration" represents residential and commercial customers as a percentage of estimated passings for the service indicated.

(d)

"Customer Relationships" include the number of customers that receive one or more levels of service, encompassing video, Internet and voice services, without regard to which service(s) such customers receive. This statistic is computed in accordance with the guidelines of the National Cable & Telecommunications Association ("NCTA"). Commercial customer relationships include video customers in commercial structures, which are calculated on an EBU basis (see footnote (o)) and non-video commercial customer relationships.

"Primary Service Units" or "PSUs" represent the total of video, Internet and voice customers.

(i)

"Quarterly Net Additions/(Losses)" represent the net gain or loss in the respective quarter for the service indicated.

(j)

"Single Play Penetration" represents residential customers receiving only one Charter service offering, including video, Internet or voice, as a % of residential customer relationships.

(k)

"Double Play Penetration" represents residential customers receiving only two Charter service offering, including video, Internet and/or voice, as a % of residential customer relationships.

(l)

"Triple Play Penetration" represents residential customers receiving all three Charter service offerings, including video, Internet and voice, as a % of residential customer relationships.

(m)

"Digital Penetration" represents the number of residential digital video customers as a percentage of residential video customers.

(n)

"Revenue per Customer Relationship" is calculated as total residential video, Internet and voice quarterly revenue divided by three divided by average residential customer relationships during the respective quarter.

(o)

Included within commercial video customers are those in commercial structures, which are calculated on an equivalent bulk unit ("EBU") basis. We calculate EBUs by dividing the bulk price charged to accounts in an area by the published rate charged to non-bulk residential customers in that market for the comparable tier of service. This EBU method of estimating basic video customers is consistent with the methodology used in determining costs paid to programmers and is consistent with the methodology used by other multiple system operators. As we increase our published video rates to residential customers without a corresponding increase in the prices charged to commercial service customers, our EBU count will decline even if there is no real loss in commercial service customers. For example, commercial video customers decreased by 10,000 during the year ended December 31, 2013 due to published video rate increases.

(a) Pro forma results reflect certain acquisitions of cable systems in 2013 as if they occurred as of January 1, 2012.

(b) See page 1 and 2 of this addendum for detail of the components included within adjusted EBITDA. Political advertising contributed to Adjusted EBITDA $1 million and $17 million for the three months ended December 31, 2013 and 2012, respectively.

The above schedules are presented in order to reconcile adjusted EBITDA and free cash flows, both non-GAAP measures, to the most directly comparable GAAP measures in accordance with Section 401(b) of the Sarbanes-Oxley Act.

Scalable infrastructure includes costs, not related to customer premise equipment, to secure growth of new customers and revenue generating units, or provide service enhancements (e.g., headend equipment).

Upgrade/rebuild includes costs to modify or replace existing fiber/coaxial cable networks, including betterments.

(e)

Support capital includes costs associated with the replacement or enhancement of non-network assets due to technological and physical obsolescence (e.g., non-network equipment, land, buildings and vehicles).

(f)

Total capital expenditures include $98 million and $88 million for the three months ended December 31, 2013 and 2012, respectively, and $319 million and $269 million for the year months ended December 31, 2013 and 2012, respectively, of capital expenditures related to commercial services.

(g)

Pro forma results reflect certain acquisitions of cable systems in 2013 as if they occurred as of January 1, 2012.
